A quality and engineering governance concept defining controls used to plan, verify, and maintain compliant product development and production. It governs requirements capture, process control, documentation, and objective evidence used to demonstrate conformity to defined standards. It does not substitute for technical performance and requires rigorous execution and traceable records to be effective. It materially affects safety, reliability, and manufacturability by reducing variation and improving defect prevention and detection. The concept is generally stable, though standards and accepted methods are revised as technology and industry practices evolve over time.

Principle

Provide explicit trace links from requirements through criteria and tests to evidence so gaps, duplications, and unresolved failures are visible and auditable.

Demonstration

A matrix row for 'pedestrian detection at dusk' lists the requirement ID, the acceptance criterion (detection ≥ 95% at 0–50 km/h at dusk), associated test case IDs, latest test result (pass/fail with date), linked sensor logs, and owner responsible for remediation.

Misapplication

Creating a matrix that contains only high-level labels without linking to concrete test IDs, raw evidence, or timestamps and then using it to claim compliance.

Consequence

A correct compliance matrix enables rapid impact analysis when requirements change, supports certification dossiers, and focuses engineering effort on uncovered risks.

Reversal

The inverted alternative is relying on informal checklists or team memory to assert compliance, which obscures traceability and increases the chance of undetected regressions.

Boundary

Intended for traceability of perception requirements and tests; it is not itself the formal safety argument but can feed into safety cases and regulatory submissions.

Semantic Tension

Related to requirements traceability matrices used across engineering, but this matrix emphasizes perception-specific acceptance criteria, sensor modalities, and evidence artifacts.

Synthesis

A structured traceability table tying perception requirements to acceptance criteria, tests, results, and evidence that makes compliance visible, auditable, and actionable.
